What architecture of client-server interaction can you advise?

Question

C++ / C#

There is a task to write the server of authorization/verification of users. Share your experience, how best to separate the transport layer from the message layer, what design patterns to use? In general, any information on this topic is welcome.

Answer 1

I discovered ProtoBuf for myself , some of the problems disappeared by themselves, but the problem with the architecture remained.

Answer 2

What about using SOA? For example JSON-RPC. Create web services and accept authorization parameters and return responses. Unless, of course, I understood your question correctly. :)

Answer 3

It is possible to use WCF. Transport is configured in the config and does not interfere with logic in any way.
